Question

I WILL MEDAL AND FAN!
Can some one explain how to solve this in synthetic division 28x^3+42x^2-35x/7x
and how you would check your quotient for accuracy.

Answer 1

Answer 2

To use sd the divisor needs to be of the form x -c. I know a tweek to the standard method that allows sd to be used when the divisor is of the form ax -b. Is this what you are asking for?

Answer 3

lol i thought you said twerkk

Answer 4

And yep thats exactly what i need

Answer 5

To use sd when the divisor is of the form ax -c:
1.) Set the divisor equal to 0
In your case you get 7x = 0, so x = 0.

Answer 6

Ok

Answer 7

2.) Set up the division problem (make sure the polynomial is in decending order, and fill in missing terms with 0's) , and use the number from step 1.)
In your case you get
0|
| 28 32 -35 0

Answer 8

ok

Answer 9

3.) You must divide the quotient by the coefficient of the original divisor that is for ax - b, you have to divide the answer you get by a:
0| 28 42 -35 0
| 0 0 0
___________________
28 42 -35 || 0 (remainder)

Answer is (28x^2 + 42x - 35) / 7

Answer 10

So the tweek :) is to divide the quotient to get the final answer.
